Term
Neurotransmitters
Definition
A. Acetylcholine
B. Norepinephrine
C. Epinephrine
D. Dopamine
E. Serotonin
Term
Acetylcholine
Definition
Function: slows the heart, controls use of voluntary muscles.
Normal amounts result in: increase muscle activity, motor coordination.
Too much ACH results in: muscle tremors, memory losses, involuntary muscle reflexes.
Complete depletion of ACH results in: confusion, hallucinations.
Term
NOREPINEPHRINE
Definition
Associated with arousal reactions and moods.
Depletion results in: depression or crash after high. Doses of amphetamines prevents reabsorption of norepinephrine.
Term
EPINEPHRINE
Definition
Powerful heart stimulant
Increases heart rate
Increases blood output
Effects: excitatory or stimulates.
Term
DOPAMINE
Definition
Function: Brains coordination and integration of fine muscular movements.
Brains memory and emotions
Unbalanced levels result in: paranoia, overly suspicious behavior, over-stimulates the fright center.
Term
SEROTONIN
Definition
Regulates sleep-wake patterns
Regulates body temperature
Prevents depression
Depletion results in: hyperactivity, insomnia, agitation, severe emotional depression.
Term
Cerebral Cortex
Definition
Responsible for receiving sensory input, interpreting incoming information and initiating voluntary motor behavior.
Term
Limbic System
Definition
Regulates emotions (fear, rage, anxiety) memory, endocrine activities
Term
Basal Ganglia
Definition
Primary centers for involuntary motor functions involving posture and muscle tone
Term
Hypothalamus
Definition
Integrates information and serves as key control center for the Autonomic nervous system (ANS)
Term
Reticular activating system (RAS)
Definition
To control the arousal level of the brain
